Baxters's Q-operators for the simplest q-deformed model
A. E. Kovalsky, G. P. Pronko
In the present paper we describe the procedure of the Q-operators construction for the q-deformed model, described by the Lax operator, which is important to formulate the Bethe an…
On the Algebraic Bethe Ansatz for XXX spin chain: creation operators "beyond the equator"
A. E. Kovalsky, G. P. Pronko
Considering the XXX spin-1/2 chain in the framework of the Algebraic Bethe Ansatz (ABA) we make the following short comment: the product of the creation operators corresponding to…
Baxter Q-operators for integrable DST chain
A. E. Kovalsky, G. P. Pronko
Following the procedure, described in the paper nlin.SI/0003002, for the integrable DST chain we construct Baxter Q-operators as the traces of monodromy of some M-operators, that a…
Doubly heavy baryons Omega_QQ' vs. Xi_QQ' in sum rules of NRQCD
V. V. Kiselev, A. E. Kovalsky
In the framework of two-point sum rules of NRQCD, the masses and couplings of doubly heavy baryons to the corresponding quark currents are evaluated with account of coulomb-like co…
